restart: Fix an error about arguments missing

Function shouldRestart() checks the restart policy and records the
debug info and there should be two arguments in the log.Debugf().

Prior to the this patch, the logs were something like this:
- client: $ docker run --restart=on-failure:3 ubuntu /bin/sh -c 'exit 1'
- daemon: INFO[0168] ...
	  DEBU[0168] stopping restart of container %!s(int=3) because maximum
	  failure could of %!d(MISSING) has been reached
	  INFO[0086] ...

Btw, fix a spelling error in the same file:
- cotnainer -> container
